Write reasons for the proofs : 3(x+2)+1=8

6x+6+1=8

6x+7=8

6x=1

x=1/6

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
